Paper Abstract

We present semi analytical, approximate model of nonlinear operation of planar waveguide laser manufactured on the base of 2D photonic crystal. We consider laser structure with F-P cavity and take into account the gain saturation effect, transverse as well as longitudinal field distribution. Our model, based on energy theory, allows to investigate in relatively easy way the influence of the real structure parameters such as photonic crystal geometry, waveguide geometry, losses as well as strength of feedback (i.e. cavity parameters) on output power level. The laser characteristics obtained reveal optimal feedback strength for given laser structure, which provide maximal power efficiency for given pumping level.
